It is carried on the public rolls at a market value of $7.1M, and assessed for tax at $3.2M. In the 71 years its record reaches back, the lot has drawn 153 separate government filings.

The documentary life of the address leans hard toward assignment: 44 of its 153 records, fully 29%, fall under that one heading. Complaint (31) and violation (26) trail well behind. 7 violations stand open against it today.

The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2026.

On the environmental ledger, the building posts an Energy Star score of 23, with a site energy-use intensity of 135.7 kBtu per square foot. Its operations answer for roughly 558 metric tons of CO2-equivalent a year.

Read together — 29% assignment, 71 years of accumulation, a parcel of Kings — these scattered records compose a portrait of the address that no single page sets out to draw.

$7.1M of Kings, written across 153 government filings.
